Abstract: A tire comprising a carcass-type reinforcement structure and beads, each bead being extended radially outwardly by a sidewall, the sidewalls meeting radially outwardly with a tread, the intersection of the sidewalls and of the tread defining the shoulder ends of the tire. The tire includes, in the area of each of the sidewalls, at least one layer of materials having a stretch rigidity in the longitudinal direction greater than 5000 daN/mm and the radially outer end of said layer of materials is radially inside the shoulder ends of the tire.

Abstract: A frequency decoupling device for decoupling a first part with respect to a second part. The device comprises a rigid outer sleeve (1) which is adapted to be secured to the first part and, positioned inside the outer sleeve, a rigid inner sleeve (2) which is adapted to be secured to the second part, an elastically deformable element (3, 4, 10) being interposed between the sleeves so as to form between the sleeves at least one annular chamber (5) containing a liquid. With the chamber having an inner perimeter “Pint”, a mean height “H” on the perimeter and a mean thickness “E” on the perimeter, the mean thickness E satisfies the following condition: E ? ( P int / 2 ? ? ) 3 200000 × H , the inner perimeter Pint, the mean height H and the mean thickness E being expressed in millimeters.

Abstract: A hydroelastic joint having first and second axial ends (B, H) spaced apart from one another along a longitudinal axis (Y) and including, at an increasing radial distance from this axis, at least one internal frame (1), an intermediate frame (2) with a window or “cage”, and an external sleeve (4), which joint also includes an elastomer packing (5) molded with at least one molding insert chosen from the assembly including the internal frame (1), the cage (2) and the external sleeve (4), in which said packing (5) at least partially forms a wall for at least two hydraulic fluid chambers (6) communicating with one another through at least one channel (30), and sealing means (3). The assembly formed by the packing (5) and each insert has at least an essentially axial molding reserve. Each chamber (6) and each channel (30) are defined inside the molding reserve and are sealed or delimited, at least in an axial direction, by the sealing means (3).
